Houghton’s first thought had been to swim out and guide the LVTs to the north bank. But the enemy had shown such unexpected resistance as to justify the withdrawal of the swimming team. The rubber boats and excess equipment were hidden along the shore and some of the weapons thrown in the river to prevent capture.[296] Then the swimmers started their return trip through water churned by mortar shells, chiefly Marine 4.2-inch bursts falling short. One of these projectiles exploded so near to Houghton as to knock him out momentarily, and he was assisted to a grounded LVT by Corporal James Morgan. The Recon commander suffered a sprained back and double vision from the concussion, and two men of the team were slightly wounded. DeFazio led the remaining swimmers to the south bank. [296] Ensign Seigle found it hard to part with his tape recorder containing an account of the venture. He hid it near the water, but the record had been erased by subsequent sounds when he retrieved it the next day. There he learned that all the amtracs had returned except the four reported grounded. Most of the Recon troops on these stranded vehicles had chosen to swim or wade back to the south bank. These stragglers were collected on the northern tip of Hill 131 by Captain John F. Paul and Corporal James P. Harney of the amtracs and shuttled to Kimpo as fast as they returned.[297] [297] 1stLt J. P. Harney interv, 17 Nov 54. DeFazio took care of his casualties, then set out with eight men in search of Houghton. It was low tide by this time, but wading through the mud proved to be more tiring than swimming. After finding Houghton in a dazed condition on one of the grounded LVTs, the sergeant agreed with Kraince and Shutler that the approach of dawn made it necessary to abandon the two amtracs which were still stuck. They returned on the two that the officers had succeeded in extricating. Thus at daybreak the swimming expedition ended in the CP of the 5th Marines, with DeFazio reporting to Murray and Brush after seeing his commanding officer on the way to a field hospital.[298] [298] DeFazio ltr, 11 Dec 54. The crews and troops on the LVTs retained a confused impression of the night’s events. Master Sergeant Edwin L. Knox, who crossed with the engineers in the second amtrac, could not understand why the column withdrew. The vehicles were dispersed in every direction after some became stuck, and it was on his LVT that Captain Houghton received first aid.[299] [299] MSgt E. L. Knox, ltr to authors, 13 May 55.
